THBVTTLENTRQL LING APPARATUS.

To nl( whom it muy verwezen.'

le it known that I, Lnwls L. SCOTT., a uitizeu oi the United States. residing in the city of tit. iiouis und Starte oi Mieeoiiri, have invented new und useful lmprovelnente in 'llirmtle-Controlling Appn itl/ns, of which the 'following is n. specification.

Th e invention relates to automobile enn gilles. und particularly to means for Controllintr the throttle of the engine. 1t hin been found that in un elnergenoy, in dri ving; n rar :i ilrix er under nervous tension is rpt to grilli the steering' wheel with lioth hunde. (ln this uri-null he muy negleet to close the throttle, though he muy have sulieient presence ol initd to apply the broke with his foot.

The gener-ui object of the present inven tion is to provide means' Ywhereby the throttle Vwill heroine automatically closed when the. brake is applied, More Speeitieally, the invention muy include u holding device. the release ot whirl is. ell'eeteil through the upA plie-ation ot' the liruke. thereby permitting the throttle valve to,close.

Further elije-rte of the invention will rippear hereinafter.

The invention insists in the generul man4 hinuiion of parts und in the features of sind parts hereinafter described, all of which eontriliutito produce :nielloient throttle control for automobile engines.

preferred embodiment oi my invention will be particularly described in the following specitiration. while the broad miope ol' my invention will lie pointed out in the up pended claims.

I prefer to provide ineens for lioliihig the vulve in the open position in which it hns loi-en not by the henri-operated lever if. und l ycontrol this holding` ineens automatici-illy hy the` operation ot the hriilzv so that when the hrulu` is applied. the throttle is permitted to lose ziutonniiirulljv. In order to accomplish this, l provide u sie ling member for actuating said brake, und mmm nulmeting Suid brake-controlling mumlmr with said gripper devia@` for :10m-- atinglr Suid gripper dorian tio release saiil vulve vontrolling means, uml thereby permit the valve to Clusif.
